• Creates an inferred JSON Schema that could be used to validate your JSON
• Quickly scan related values to check for edge cases

Features

Column view

Inspired by macOS Finder, Column View is a new way to browse a JSON document.

It has all the features you'd expect: Keyboard navigation, Path bar, history.

It also has a nifty feature that allows you to "hold" a descendent selected and travel up through the hierarchy, and then move between siblings and view the different values found at that path. It's hard to describe, but here is an animation to help demonstrate:

As you can see, holding the Option (or Alt key on Windows) while moving to a parent keeps the part of the document selected and shows it in context of it's surrounding JSON. Then you can traverse between items in an array and compare the values of the selection across deep hierarchy cahnges.

Editor view

View your entire JSON document in an editor, but keep the nice previews and related values you get from the sidebar as you move around the document:

Content Previews

JSON Hero automatically infers the content of strings and provides useful previews and properties of the value you've selected. It's "Show Don't Tell" for JSON:
